NORMAN '1. MlLLS, or CAMBRIDGE, MASSACHUSETTS,

BICYCLE-BELL.

SPECIFICATION forming part of Letters Patent No. 562,638, dated June 23, 1896.

Application filed March 25, 1895.

To all whom it may concern:

Be it known that I, NORMAN T. MILLS, of Cambridge, county of Middlesex, State of Massachusetts, have invented an Improve ment in Bicycle-Bells, of which the following description, in connection with the accompan ying drawings, is a specification, like letters on the drawings representing like parts.

This invention has for its object the improvement of gong bells wherein the hammer-carrier has imparted to it a rotating motion.

One feature of my invention relates to the construction of the hammer-carrier, whereby a strong resonant sound is produced without any rattling of parts when the bell is operated.

Another feature of my invention relates to the construction of the gong, wherebya chiming is produced when the bell is sounded.

Other features of my invention will be hereinafter described, and particularly point ed out in the claims.

Figure 1 is a vertical sectional View of a gong-bellv embodying my invention, taken on the line a: m, Fig. 5. Fig. 2 shows in plan view the base and actuating mechanism of the bell, the gong being removed. Fig. 2 is a perspective view of the internally-toothed rack or gear. Fig. 3 is an under side View of the gong. Fig. 4: is a top view of the gongbell shown in Fig. 1. Fig. 5 is a side elevation thereof, partially in section. Fig. 6 is a detached view in elevation of a modified form of hammer-carrier. Figs. 7 and 8 are details of the clip for securing the bell in position, and Fig. 9 is a plan view of the key for actuatin g the clip.

The base a, having suitable clip-supporting cars a, and a threaded post a rising from its upper side, are and may be as common to this class of bells. A stub b, rising from the base at one side of the post (1?, serves as a pivot for a pinion b, having an attached gear 29 and at the other side of the post a I have shown another pivot-stud d fixed to the base (see Fig. 1) for the hub (Z of the actuator, (shown as an internally-toothed segment gear d, connected to the hub by an arm (1 said hub being provided with a handle d A spring .9, suitably secured at one end to the base by a pin (1 (see Fig. 2) and at its other end to an ear Serial No. 543,045. (No model) (1 of the hub d, normally holds the segmentgear in the position shown in Fig. 2. The post a is surrounded loosely at its lower end by the hub of a pinion o, engaged by the actuator 62-, said pinion being connected to an internally-toothed rack or gear 0, the teeth of which are in engagement with the pinion Z).

The hub of the pinion c has a sleeve-like extension o upon which is loosely mounted a pinion f, resting upon the central portion of the rack c, and to the pinion f is rigidly connected a hammer-carrier f", the teeth of the gear 11 engaging the teeth of said pinion f.

I have herein shown the hammencarrierf as a thin plate upturned at its ends to form support-s f for two hammers f loosely connected thereto by suitable eyes or loops f at their outer sides, said supports preventing a planetary motion of the hammers on thehammer-carrier as the latter is revolved.

To prevent rattling of the hammers, (herein shown as spherical,) I have interposed springs s between the hammers and their supports, and surrounding the eyes orloopsf as clearly shown in Figs. 1, 2, and 6, the springs expanding and contracting as the speed of rotation of the hammer-carrier is increased or diminished.

Movement of the handle (1 in the direction of the arrow 30, Fig. 2, will move the actuator d and the intervening in echanisni to cause the hammer-carrier f to rotate rapidly in one direction, the spring 3 causing its rotation in the other direction.

It will be obvious that the hammer-carrier will be rotated many times for each movement of the actuator, giving a great number of quick blows.

I have herein shown a chiming-bell, that is to say, one in which a plurality of different tones sound simultaneously, producing a very pleasing effect upon the ear, and in this instance the chiming is ett'eot-ed by employing two gongs h 'i, of different tones, and adapted to be rung by the rotation of the hammercarrier.

The gong h is provided with a threaded boss 71' to screw upon the threaded post a as shown in Fig. 1, said boss keeping the hammer-carrier in place, said gong having upon its interior a projection 7L2 to be struck by to rotate in the same plane, and to cooperate therewith both gong projections would be in the same plane, each being struck by both I 5 hammers.

I preferably make openings 17 in the outer gong to obviate any muffling of the sound of the inner gong, and such openings do not detract from the clearness of tone of the gong 20 in which they are made.

-A lug i on one gong may enter a depression in the other, as shown in Fig. 1, to keep the gongs from rotating, if desired.

The cars a of the base are connected by a pin a and by a web a, provided with ahole for a clip-adjusting screw m, having a head on oppositely nicked at m which is provided with an undercut annular groove to receive thereon a rotatable cap m havinga nick m 0 the cap having overturned ears which enter the annular groove in the head and retain the cap rotatably thereon. When the nicks of the head and cap register, the screw m may be rotated by'a forked key k, the prongs 3 5/thereof passing through the nick m into the nicks m in the head of the screw, Fig. 9, but if an ordinary screw-driver be used the cap m may be rotated indefinitely without moving the screw, thus serving as a locking 4o device.

The clip consists of apiece of thin metaln turned inward at its ends, as at n 11. and perforated to receive the screw m.

An internally-threaded block a is secured to the clip within one of the inturned ends, as n, and when the clip is bent to cause the ends to overlap, they can be inserted between the cars a, and the screw m rotated to engage the block n drawing the loop of the clip close against the under side of the base and the pin a When it is desired to secure the bell in place, the clip is passed around some suitable object, as the handle-bar of a bicycle, and

then replaced and tightened by the screw m, as described, using a key is or similar device, and owing to the peculiar construction of the head of the screw the clip is locked in position so that the bell cannot be removed except by breaking or severing the clip.

While I have herein shown a chiming-gong, it is obvious that the hammer herein shown is not restricted thereto, as it is equally well adapted to other gong-bells having but a single gong.

I claim 1. The base, and a plurality of gongs attached thereto one within the other, each gong having a hammer-engaging portion projecting from its inner side, combined with a hammer movable in a circular path, and means to operate the hammer to sound each of the gongs, the hammer-engaging portion of the outer gong being extended through an opening in the inner gong, substantially as described. v

2. In a chiming-bell, a plurality of gongs, one within the other, each having an inturned projection, combined with a single hammercarrier provided with striking-hammers, the means to rotate said hammer-carrier to sound the gongs, substantially as described.

3. The base; a plurality of gongs attached thereto, one within the other, and a projection on the inner side of each gong, combined with a hammer-carrier provided with an upturned support, a spring-controlled hammer, loosely connected to said support at its outer side, and means to rotate the hammer-carrier to bring its hammer into engagement with the projections of the gongs, substantially as described.

4. In a gong-bell, a rotatable hammer-carrier having an upturned support, a hammer positively and loosely connected thereto at its outer side and being sustained only by said support, a spring interposed between the outer side of said support and the hammer, and means to rotate the hammer-carrier to ring the bell, substantially as described.

5. The base, and a plurality of gongs attached thereto, one within the other, each gong provided with a projection, said projections being in different planes, combined with a rotatable hammer-carrier,two hammers thereon at different heights to engage respectively said projections, and means to rotate the hammer-carrier to ring the gongs, substantially as described.

6. In a bicycle-bell, a base, an adjustingscrew rotatably mounted therein, and an attaching-clip inturned at its inner ends and perforated, and an internally-threaded block secured to the clip within one of its inturned ends to engage the screw, whereby when the clip is bent to cause its ends to overlap, engagement and rotation of the adj usting-screw will draw the loop of the clip into the base, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
